SONET SONET OC-1 (optical carrier one) is a SONET line with transmission speed of 51.84 Mbit/s ( payload: 50.112 Mbit/s; overhead: 1.728 Mbit/s) using optical fiber. This base rate is multiplied for use by other OC-n standards. For example, an OC-3 connection is 3 times the rate of OC-1. ...more on Wikipedia about "OC-1"
OC-12 ( Optical Carrier 12) is a fiber optic network line with a SONET rate of 621.84 Mbit/s ( payload: 601.344 Mbit/s; overhead: 20.736 Mbit/s) or 12 times the basic SONET signal transmitting rate of 51.84 Mbit/s ( OC-1). ...more on Wikipedia about "OC-12"
OC-1536 is a SONET line with transmission speed of about 80 Gbit/s using optical fiber. ...more on Wikipedia about "OC-1536"
OC-192 (Optical Carrier 192) is a fiber optic network line with a SONET rate of 9953.28 Mbit/s ( payload: 9621.504 Mbit/s; overhead: 331.776 Mbit/s), or 192 times the basic 51.84 Mbit/s SONET signal ( OC-1), hence the name OC-192. 10 Gigabit Ethernet is also designed to interoperate with OC-192. This is the fastest connection commonly available to the internet. The OC-768 is the next increment in speed increase over OC-192, operating at 39,813.12 Mbit/s. ...more on Wikipedia about "OC-192"
OC-24 is a SONET line with transmission speed of 1.244 Gbit/s using optical fiber. ...more on Wikipedia about "OC-24"
OC-256 is a SONET line with transmission speed of about 13 Gbit/s using optical fiber. ...more on Wikipedia about "OC-256"
OC-3 ( Optical Carrier 3) is a network line with transmission speed of 155.52 Mbit/s ( payload: 150.336 Mbit/s; overhead: 5.184 Mbit/s) using fiber optics. Depending on the system OC-3 is also known as STS-3 (electrical level) and STM-1 ( SDH). ...more on Wikipedia about "OC-3"
OC-3072 is a SONET line with transmission speed of about 160 Gbit/s using optical fiber. ...more on Wikipedia about "OC-3072"
OC-384 is a SONET line with transmission speed of about 20 Gbit/s using optical fiber. ...more on Wikipedia about "OC-384"
OC-48 ( Optical Carrier 48) is a fiber optic network line with a SONET rate of 2488.32 Mbit/s ( payload: 2405.376 Mbit/s; overhead: 82.944 Mbit/s) or 48 times the basic SONET signal transmitting at 51.84 Mbit/s. ...more on Wikipedia about "OC-48"
OC-768 is a fiber optic network line with a SONET rate of 39,813.12 Mbit/s ( payload: 38,486.016 Mbit/s; overhead: 1327.104 Mbit/s), or 768 times the basic SONET rate of 51.84 Mbit/s ( OC-1). As of 2005, use of OC-768 connections outside of research or testing networks is very rare, because they are extremely expensive. However, it is the next logical speed step in what has been a very successful and popular connection standard ( SONET) so the widespread adoption and use of this standard in the future is predicted. ...more on Wikipedia about "OC-768"
OC-n, or Optical Carrier n is a SONET standard designating multiplier as compared to an OC-1 connection; which has a line rate of 51.84 megabits per second. An OC-3 is 3 times the line rate of an OC-1, an OC-12 is 12 times greater. ...more on Wikipedia about "OC-n"

The STM-1 (Synchronous Transmission Module) is the basic rate of transmission of the SDH ITU-T fiber optic network transmission standard. It has a bit rate of 155.52 Mbit/s and is the SDH equivalent of an OC-3 ( SONET). ...more on Wikipedia about "STM-1"
The Synchronous optical network, commonly known as SONET, is a standard for communicating digital information using lasers or light emitting diodes (LEDs) over optical fiber as defined by GR-253-CORE from Telcordia. It was developed to replace the PDH system for transporting large amounts of telephone and data traffic and to allow for interoperability between equipment from different vendors. ...more on Wikipedia about "Synchronous optical networking"
